A warped roof like what you seem to want is either a roof-framers nightmare or his crowning achievement, as it will require tiny pitch changes with each set of rafters, bending sheathing, and more fun things. Also, it is impossible to draw using Chief roof tools, which only produce flat planar or cylindrical surfaces.

What software you using? And on what machine? Take the time to go to your profile and create a signature text, so we can better help. Here is a dimensioned wall detail. Is this what you want to do?

Show us all you have to work with. Pictures, plan views, elevations, etc. Your "backing onto a rock wall" thing needs to be better explained. Attach all directly, and not as downloads, please. As for how-to, Chief has many many instructive videos.

I think you have another case of a plan drawn in 2D by someone who didn't use 3D to generate elevations, thus you may have something you cannot replicate in Chief.

Gotta wait for Chief. This, and more, has been suggested as needed stair tool additions.

I've a simple one floor house and have truss-framed the roof, and now want a six-truss run, 10 feet in length, to all be attic trusses so we can have a platform deck on which to mount HVAC equipment. The depth of the bottom chord for the rebuild is unknown but it's certainly not 3.5". Do I just draw my "room" with invisible attic walls and guess the floor structure at, say, 7.25"? And the rebuild the affected trusses?

I did not download, but have a q. "glass panel, with 1/2" lites" Do you mean 1/2" muntins?

This presumes you need us to look at something in the building. Copy it, then strip the copy of all that is not stuctural. Remove terrain, fixtures, furniture, clean off any weird textures you may have applied, the file is to contain no plants, no people, no nothing but walls, floors, roofs, windows and doors.

I hope I stated this so as to be understood. I need a larger scale for some details I want to do, and having a default set for 1" = 1'-0", went ahead and wrote a new default set for 1 1/2". I had already created a text style for this new scale. I'll need to write the appropriate specs for rich text, arrows, callouts, and the rest, but for now I am starting with text. See here that my newly created text style appears in the lineup. Now see here, in this screencap of the default set dialog, I cannot see the text style in the dropdown, and thus cannot assign it to this default set. What am I missing?

Pretty long discussion for a Home Designer 2026 issue.

I made a house with enough roof area to do what I wanted, then manually cut a hole in the roof and built the dormer walls connected to interior walls so as to have it be a "room" with a ceiling and roof over, then used a different wall type to draw the three balcony walls, and manually adjusted their shapes. It's a mess, but it's a start. You can use the window tool, pass-through type, to make the scuppers. If you can shape windows into a trapezoid, you can shape pass-throughs. I think the glass and metal railings will need to be modeled manually using whatever you like. Solids would be my choice. Others might use cabinets.

Did you see this? https://www.chiefarchitect.com/videos/watch/5202/creating-floor-platforms-that-hang-inside-walls.html?playlist=144 Try building with a 4-1/2" thickness mudsill and then editing it to a 3-stack after your framing is all the way you want it.

Why three? Is it to get your wall finish closer to grade?

Raise the larger roof plane 10 inches? Those rafters likely bear on a plate atop the floor frame.
